BED-DAVENPORT.

Application filed. April 9, 1913.

To all whom it may concern:

Be it known that I, ADOLPH C. KLOPPING, a citizen of the United States,and a resident of Toledo, in the county of Lucas and State of Ohio, haveinvented a certain new and useful Bed-Davenport; and I do hereby declarethe following to be a full, clear, and eXact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

This invention relates particularly to means for locking the sections offolding bed davenport frames in folded form, but is not restricted tosuch use as it may be used in any connection for which it may be adaptedor appropriate.

The object of my invention is the provision of improved means forlocking two bed frame sections together in spaced folded relation, andwhich is automaticallyoperable by the unfolding movement of a legpivotally carried by one frame section to release the locking connectionof the sections, whereby to enhance the practicability and commercialvalue of apparatus of this class.

The invention is fully described in the following specification, andwhile, in its broader aspect, it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawings, in which,-

Figure 1 is a side elevation of a bedframe partly unfolded and equippedwith the invention, and with the complete unfolded position thereofshown in dotted lines, and Fig. 2 is an enlarged side elevation of theinvention in section locking position, with the released positionthereof shown in dotted lines.

Referring to the drawings, 1 and 2 designate two adjoining sections of abed-frame, which, in the present instance, are pivotally connected ateach side by a link 3 to permit such sections to be folded one over theother with the adjoining ends spaced by the links 3, as shown, to allowfor the thickness of a mattress disposed on the bedframe and foldabletherewith. A supporting leg 4: is pivoted to each of the outer cornerportions Specification of Letters Patent.

of the frame section 2, as at 5, for rearward folding movements againstthe side thereon, and, when in upright or frame supporting position, isbraced by a link-member 6, which is pivoted at one end to the leg andhas its other end portion provided with a hook-shaped slot in which apin 7 on the frame section works. The outer end of the frame section 1issupported'at its sides in a similar manner by legs 8, and its inner oropposite end is supported by a supporting frame 9, or in any othersuitable manner, as is well understood in the art.

A catch-member 10 is pivoted to each outer corner portion of theframe-section 2 for rocking movements longitudinally there of, beingpivoted, in the present instance, as at 11, to a plate or part 12, whichprojects downward from the section side when such section is in itsfolded position relative to the section 1. Nhen the sections are in thefolded relation shown, each catch-member 10 (it being understood thatone is disposed at each side of the frame) depends or hangs in suspendedmanner from the section 2 and has a notch 13 in the front or outer edgeof its nose portion in engagement with a stud 14: on the side of theframe section 1, which stud cooperates with the catch member to hold thesections in rigid spaced relation.

A coiled compression spring 15 is disposed between a spur or projection16 on the.

inner edge of the catch-member 10 and a reg istering portion of the part12 to yieldingly hold the catch-me1nber in engagement with the stud 14.The inner end of the catch member 10 is extended beyond its pivot and isprovided at its outer edge with a trans versely projecting flange 17,which coacts with the outer end of the bed frame section 2 to limit thespring influenced movements of the catch member 10 when not in engageherwith the stud 14 upon a lowering of the catch-member with the section 2into studengaging position.

' retracting movement of the members against the tension of the spring15 until the members have lowered suiiiciently to place thestud-receiving notches thereof into register with the studs 14, thesprings then acting to. force the members into notched engagement withthe studs, as is apparent. The studs 14 coact with the opposite walls ofthe member notches to prevent a longitudinal movement in eitherdirection of the members relative to the frame section 1, thus retainingthe two sections in rigid spaced relation. The legs 4 may be foldedagainst the section 2 either before or after the engagement of themembers 10 with the studs 14, but it is preferable to first fold thelegs against the frame section as a movement of the legs from upright tofolded position causes a momentary stud-releasing movement of thecatch-members. When it is desired to unfold the frame sections theoperator grasps the legs 4 and imparts suflicient unfolding movementsthereto relative to the section 2 to cause their inner ends 18 to act onthe flanges 17 of the catch-members to retract the notched ends of themembers from engagement with the studs 14, thus permitting the outerframe section to be unfolded from over the section 1.

It is evident that this construction of section locking means isentirely automatic in its engaging action upon a relative foldingmovement of the sections 1 and 2, and that its releasing movements arecontrolled by unfolding movements of the legs 4, thus 1 providing alocking means which is exceedingly simple to operate and requires noattention on the part of the operator. It is also evident that theyielding pressure of the inner flanged end of the catch member 10 on theprojected inner end 18 of the leg 4 tends to retain such leg in itsfolded position, as shown in the drawings, until an unfolding stress isapplied thereto, thus preventing a free pivotal movement of the leg fromfolded position when the frame sections 1 and 2 are inverted from theposition shown upon a further folding action of the bed frame.

I wish it understood that my invention is not limited to any specificconstruction or arrangement of the parts except in so far as suchlimitations are specified in the claims.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is,

1. In combination, a set of foldable hinged sections, one section havinga projection, a latch member pivoted to the other section and operableto engage said part and to cooperate therewith to firmly space thesections when in folded position, means urging an engagement of themember with said proj ection when in engaging position, and a legpivoted to the section carrying said member and having its inner endportion extended and operable to coact with a portion of said member tomove it from engagement with said part when initial unfolding movementsare imparted to the leg.

2. In combination, a bed frame having outer and inner foldable hingedsections, a leg pivoted to the outer section, and a pivoted catch-membercarried by the outer section and operable to have locking engagementwith a part of the inner section when the outer section is foldedthereover, means urging a movement of said member in one direction, saidleg and member having their inner end portions in yielding contactwhereby a movement of the leg from folded position imparts a releasingmovement to said member.

3. In combination, a bed frame having an outer and inner sectionfoldable one over the other, a'leg pivoted to the outer section andhaving a projection at its inner end, a catchmember pivotally carried bythe outer section and normally standing in upright position relativethereto, said member being adapted to have locking engagement with apart of the inner section when the sections are in folded position andhaving a flange projecting laterally from one edge thereof in the pathof oscillatory movements of the inner end projection of said leg wherebya movement of the leg from folded position will communicate asection-releasing movement to said member, and means influencing amovement of the catch-member in one direction.

4. In combination, a plurality of foldable bed frame sections, a legpivoted to one of said sections, a section locking device movablycarried by the section with said leg and controlled by movements of theleg, and means acting on said device to cause it to yieldingly retainthe leg in either set-up or folded relation to the carrying section.

5. In combination, a plurality of foldable bed frame sections, a legpivoted to one of said sections, a catch member yieldingly carried byone section for yielding movements relative thereto and adapted toengage a part of another section to retain the sections in foldedrelation, and means acting through said catch member to yieldinglyretain the leg in folded position relative to its carrying section.

6. In combination, a plurality of foldable bed frame sections, a legpivoted to one of said sections, and a catch member carried by thesection with said leg for pivotal movements relative thereto andoperable to have catch engagement with a part of another of saidsections, means urging a movement of said member in one direction, saidcatch member and leg having parts thereof in camming coaction wherebythe catch member yieldingly acts on the leg when in folded position toretain it in such position and a movement of the leg from foldedposition imparts unlocking movements to the catch member.

In testimony whereof, I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.
